Classification is made on the basis of a clear definition.5) In order to make a clear and logic classification, one needs to follow a principle ofclassification and go on with a system consistently. For example, the categories of classification should be mutually exclusive and no overlapping is allowed.Reading 1 Causes for Global Warming2. Coal is the most abundant fossil fuel resource. It provides about one-quarter of the totalenergy the world uses, and 40 percent of the electricity generated worldwide is powered by coal. The steel industry also is greatly dependent upon this fossil fuel. Like other depletingsources of global energy, coal reserves are also on a steep decline. Moreover, coal is a greenhouse gas nightmare. Natural gas is comprised mostly of methane, although it also contains ethane, propane and butane. It is a convenient and efficient energy source. The major consumers of natural gas are the residential, commercial and industrial sectors. It is also used to generate electricity. Unlike other fossil fuels, natural gas is cleaner and causes less pollution. Like other fossil fuels, this resource is depleting rapidly.Task 2 Understanding Lectures through ClassificationListening 11.

Id functions on “the Pleasure Principle”, while ego works on “the Reality Principle” and superego is the internalized rules of a society. Ego is in between id and superego.Task 3 Reading Classification ArticlesReading 2 Renewable Energy Sources—A Brief Summary1. 1) Renewable energy is energy which comes from natural resources such as

What’s more, there is a health factor that affects both of them. Canned food loses some of theoriginal fresh food nutrients when stored, and also has to be tinned with many preservatives and chemical factors that prolong the shelf life and apparent freshness of the food but could become toxic if consumed too often. Fresh food, on the other hand, often comes straight froma farm and has all the nutrients Mother Nature intended for it. As we can see, fresh foodoffers many benefits that canned food lacks.

For secondary hypertension, there are kidney diseases, tumors or other abnormalities.2) For essential hypertension, the supporting evidences are“high blood pressure tends to run in families and is more likely to affect men than women. Age and race also play a role. In the United States, blacks are twice as likely as whites to have high blood pressure, although the gap begins to narrow around age 44. After age 65, black women have the highest incidence of high blood pressure”; the link between salt and high blood pressure is especially compelling. For secondary hypertension, the supporting evidence is“hypertension can also be triggered by tumors or other abnormalities that cause the adrenal glands (small glands that sit atop the kidneys) to secrete excess amounts of the hormones that elevate blood pressure”.3) To organize supporting details, the following three sequences can be adopted: —Chronological order;—Order of importance;—Categorical order.4) The common transitional words and phrases are: because, contribute to, also, the underlying cause, other factors, and the known causes.。

It involves gathering observable, empirical and measurable evidence, the collection of data through observation and experimentation, and the formulation and testing of hypotheses.2)Scientists put forward hypotheses to explain what is observed. They then conduct experiments to test these hypotheses. The steps taken in the experiment must be capable of replication and the results emerge as the same. What is discovered may lead to a new hypothesis.3) Scientists are human and can be unintentionally biased; total objectivity is impossible.4) Scientists are human and can be unintentionally biased. Science uses our senses and our senses can be mistaken. We can never understand something as it really is because our very presence affects what is being studied.5) ①Science is both a body of knowledge and a process.②Science is exciting.③Science is useful.④Science is ongoing.⑤Science is reliable.⑥Science is a community endeavor.2. 1) c 2) g 3) e 4) f 5) a 6) d 7) h 8) k 9) b 10) i 11) j4.

They always fitted and were always confirmed.4) Light must be attracted by heavy bodies (such as the sun).5) There is the risk involved in a prediction: the theory is incompatible with certain possible results of observation —in fact with results which everybody before Einstein would have expected.4.

Instead, try to explain what might have been wrongwith your original hypothesis.4) An important thing to remember during this stage of the scientific method is that once you develop a hypothesis and a prediction, you shouldn’t change it, even if the results of your experiment show that you were wrong.5) Because there is a chance that you made a miscue somewhere along the way.7.

In thisprocess, one should expect an event which could refute the theory. Only through beingrefuted by new observations which are incompatible with the theory could it be falsified,which ref lects its truescientific virtue.2) A hypothesis is a possible solution to a problem, based on knowledge and research, while a theory is a hypothesis confirmed by the research findings. Every theory cannot be applied to every situation; otherwise, it is not a good theory.3) It is always possible to verify nearly every theory, but that would rescue the theory from refutation at the price of destroying, or at least lowering its scientific status.4) To falsify a theory is more valuable, because a theory which is not refutable by any conceivable event is non-scientific.9. 1) Because of this personal experience and an interest in the problem, you decide to learn moreabout what makes plants grow. (Para. B)2) The experiment that you will design is done to test the hypothesis. (Para. D)3) Through informal, exploratory observations of plants in a garden, those with more sunlightappear to grow bigger. (Para. H)4) The judges at your science fair will not take points off simply because your results don’tmatch up with your hypothesis. (Para. K)5) You cannot prove the hypothesis with a single experiment, because there is a chance that youmade a miscue somewhere along the way. (Para. Q)10. Observation, the initial stage of the research, requires a thorough understanding of a researchproject you have chosen by collecting adequate information from various sources, and isfollowed by the next stage known as hypothesis, an uncomplicated statement that defines what you think the outcome of your experiment will be.Exploring the Topic4. 1) Science does not include explanations based on no empirical evidence.2) The human nature of science, however, renders it unlikely to be free of personal prejudices,misapprehensions, and bias.3) The scope of science encompasses the whole universe and natural world.4) Science is a process of deciding whether the acquired evidence may prove what is mostlikely to be correct currently.5) It is not possible to prove a hypothesis with a single experiment, as chances are that amistake was made somewhere in the process.Integrated Exercises2.

The scientificmethod is a series of steps that serve as guidelines for scientific efforts, and a tool thathelps scientists solve problems and determine answers to questions in a logical format.There are two forms of scientific method: the experimental method and the descriptivemethod. The former employs numerical data and graphs, used in physical sciences, whilethe latter gathers Information through visual observation and interviewing, employed inzoology and anthropology. The scientific method involves five steps, namely, identifying a problem, researching the problem, formulating a hypothesis, conducting an experiment and reaching a conclusion.C. (1) The process of science, in contrast to the linear steps of the simplified scientific method,is iterative.(2) Science circles back on itself so that useful ideas are built upon and used to learn evenmore about the natural world.(3) Gregor Mendel showed that inheritance is particulate that information is passed along indiscrete packets that cannot be diluted.(4) Any point in the process leads to many possible next steps, and where that next stepleads could be a surprise.(5) Science may involve many different people engaged in all sorts of different activities indifferent orders and at different points in time.D.

Reading 1 tends to be factual, while Reading 2 is more critical of the factthat the Chinese are ignorant of their ancient achievements and the Westerners simply take them for granted.2) The argument in Reading 2 is more reasonable and acceptable since the author uses a lot ofexamples and examines the question from both the Chinese and Western perspectives to illustrate his point.3) Reading 2 holds more obvious negative attitudes towards Westerners.4) It would be better if the nations and the peoples of the world had a clearer understandingof each other, allowing the mental gap between East and West to be bridged. (Reading 2) The discoveries and inventions made in Europe in the seventeenth century and thereafter depended so much in so many cases on centuries of previous Chinese progress in science, technology and medicine. (Reading 3)9. 1) He regarded the origins of these inventions as “obscure”and he died without everknowing that all of them were Chinese. (Para. B)2) Chauvinistic Westerners, of course, always try to minimize the indebtedness of Europe toChina in the ancient and the Middle Ages, but often the circumstantial evidence iscompelling. (Para. C)3) In many cases we simply cannot identify the channels through which knowledge wasconveyed from East to West. (Para. C)4) Modern science which developed in the seventeenth century was a mathematization ofhypotheses about nature, combined with experimentation. (Para. D)5) One factor which must have great relevance here is the circumstance that the feudalism ofEurope and China were fundamentally different. (Para. E)10.The feudalism of China differed greatly from that of Europe in that its bureaucraticorganization promoted the growth of science in ancient China but inhibited its furtherdevelopment later on.Exploring the Topic4. 1) Increasingly being bewitched by the advanced European technology, the Chinese haveforgotten their own achievements.2) A book like that would be absolutely non-academic; it would nevertheless have afar-reaching influence on the general history of thought and ideas.3) The lesson to be drawn from the history of agriculture can best illustrate the ignorance ofthe egoistic westerners.4) The Chinese and Westerners are equally surprised when they realize that modernagriculture, modern shipping and even the essential design of the steam engine alloriginated from China.5) A clear understanding among the nations and the peoples of the world would be welcomedto bridge the gap between East and West.5. 2) The deafening noise, and the glare of the engine fire, would have a bad effect on nerves.Further, being moved through the air at a high speed would do great injury to delicatelungs. The sudden plunging of a train into the darkness of a tunnel, and the equally sudden rush into full daylight, would cause great damage to the eyesight.3) What was it that enabled them to become great or successful? Were they born withsomething special? Or did their greatness have more to do with timing, devotion and,perhaps, an uncompromising personality? The answer is a never surrender attitude. If great achievers share anything, it is an unrelenting drive to succeed. There is a tendency to think that they are endowed with something super-normal.Integrated Exercises2.

Your essay should cover the following points:- The increasing demand for energy and the challenges of relying on fossil fuels.- The benefits of renewable energy sources, such as solar,wind, and hydroelectric power.- The role of technology in advancing renewable energy solutions.- The economic and environmental implications of a transition to renewable energy.- The need for policy support and public awareness to promote the adoption of renewable energy.Sample Essay:The 21st century has ushered in an era of unprecedented energy demand, driven by global population growth and industrialization. Traditional fossil fuels, while abundant, present significant challenges, including environmental degradation and the potential for resource depletion. In contrast, renewable energy sources offer a sustainable alternative that can help mitigate these issues.Renewable energy, derived from the sun, wind, and water, among other sources, is inexhaustible and clean. Solar panels convert sunlight into electricity, wind turbines harness the power of the wind, and hydroelectric dams utilize the force of flowing water. These technologies not only reduce greenhouse gas emissions but also decrease our dependence on finite resources.Advancements in technology have made renewable energy more efficient and cost-effective. Innovations in energy storage and grid integration are addressing the intermittency of renewable sources, making them more reliable and accessible. Furthermore, the transition to renewable energy is aneconomic opportunity, with the potential to create new jobs and stimulate growth in the clean energy sector.However, the shift to renewable energy requires robust policy support and public awareness. Governments must enact incentives for renewable energy development and implement regulations that reduce the environmental impact oftraditional energy sources. Public education campaigns can also play a crucial role in fostering a societal understanding of the benefits of renewable energy and encouraging its adoption.In conclusion, the importance of renewable energy in the 21st century cannot be overstated. As we face the dual challenges of energy scarcity and environmental sustainability, renewable energy offers a promising path forward. With continued innovation, policy support, and public engagement, we can harness the power of the sun, wind, and water to build a cleaner。
